Application August 24,

3 Claims.

My invention relates to interlocking shingles and the roofing produced thereby.

An important object of the invention is to provide a shingle carrying an interlocking element permanently' attached thereto and which serves as a gauge for locating and spacing the adjacent companion shingle in the same line.

A further object of the invention is to provide interlocking shingles which are securely held in position upon a roof against improper displacement, but are capable of slight relative movements due to expansion and contraction.

A further object of the invention is to provide a roofing which is attractive in appearance,

ly laid.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying drawing forming a part of this application and in which like numerals are employed to designate like parts throughout the same,

Figure 1 is a plan view of the shingles embody- 25 ing my invention, assembled to produce a roof section,

Figure 2 is a perspective view of one of the` shingles,

Figure 3 is a detailed section taken on line 3-3 Figure 1, and,

Figure 4 is a similar view taken on line 4--4 of Figure 1.

In the drawing, wherein for the purpose of illustration is shown a preferred embodiment of y my invention, the numeral I0 designates a exible shingle. This is preferably a composition shingle although the same may be formed of metal or other material. The lshingle is a parallelogram and is preferably square. The lower corner of the shingle is cut off providing a horizontal edge II, and its oppositely. arranged side corners are also cut 01T, providing vertical edges I2 and I3, while the upper corner of the shingle is not cut 01T but continues to a point. Permanently se- 45 cured to and preferably formed integral with the shingle Ill at the vertical edge I3 is a locking device comprising a horizontal strip I4, having a vertical edge I5. Formed upon the lower horizontal edge of the strip I4 is a shank IB having a laterally extending tongue I 1. The shank I6 is straight and has a suicient length, such as approximately 1X2 or, more, to permit the slight movement 'of creeping of the companion shingle interlocked therewith, due to changes in temperature or the like. The shingle I0l is provided durable, and one which may be readily and cheap- I Jr., Florence,

adjacent to its lower horizontal edge II with a U-shaped slit I8, disposed at 90 degrees from the locking device I4. Tongue II is adapted to be inserted through the slit I8 and will engage over the companion shingle, while the shank I6 will 5 be held vwithin this slit. I

In assembling the shingles to produce a roof, a lowermost horizontal row of shingles is provided, by arranging the shingles in the row, with the edges II lowermost. The strip I4 of one 10 shingle contacts with the vertical edge I2 of thev adjacent companion shingle and serves as a gauge for arranging .and spacing the shingles. The shingles are nailed down, as shown at I9, 20 and 2|. jacent to the strip I4 integral therewith, nail 20 passes through the strip I4 at its center while nail 2I passes through the adjacent companion shingle adjacent to its vertical edge I2. The shingles in the next upper horizontal row are now 20 assembled, and the tongue I6 of the lower shingle is inserted through the slit I9 of the corresponding shingle in the next upper row, thereby locking down the lower end of the upper shingle, so that it is held down against curling or rising. The shingles in the upper row overlap the shingles in the next lower row, as shown. The shank I6 permits of a slight or limited movement of the adjacent shingle due to heat changes or the like. When the shingles are placed in position to form the roof they are in diamond formation. Each shingle has a square or rectangular body portion, and the opposed lower edges of each body portion converge downwardly while the upper opposed edges converge upwardly, forming upper and lower corners and intermediate corners. The strip I4 has its longitudinal axis horizontal, and the converging opposed upper and lower edges of the body portion are arranged oblique with respect to this longitudinal axis. The slit I8 is 40 arranged at the lowermost corner. of the body portion, and the slit is horizontal, and the cony verging edges of the body portion are oblique with respect to the slit, and the ends of the slit are closed.

It is to be understood that the form of my in- "vention herewith rshown and described is to be taken as a preferred example of the same and that various changes in the shape, size, and arrangement of parts may be resorted to, without departing from the spirit of my invention, or the scope of the subjoined claims. v

Having thus described my invention, what I claim is:

l. A roong comprising a plurality of shingles The nail I9 passes through the shingle ad- 15 l arranged in diamond formation, the shingles being disposed in horizontal rows, each shingle comprising a substantially rectangular body portion having opposed lower downwardly converging edges and opposed upperupwardly converging edges forming upper and lower corners and intermediate corners, each shingle having a strip permanently secured thereto at one intermediate the lower corner of the shingle in the next upper horizontal row.

2. In a roofing, a shingle having a body portion which is substantially rectangular, said body portion having opposed lower downwardly converging edges and opposed upper upwardly con verging edges forming upper and lower corners and intermediate corners, the shingle having a strip permanently secured thereto at one corner and projecting beyound the corner, said strip having a downwardly extending tongue, said strip having its longitudinal axis substantially horizontal and the opposed converging edges of the body portion being diagonal with respect to the longitudinal axis of the strip, the body portion being provided adjacent to its lower corner with a slit.

3. In a roofing, a substantially square shingle having a body portion provided with opposed lowf er downwardly converging edges and opposed upper upwardly converging edges forming upper and lower corners and intermediate corners, the shingle having a substantially horizontal strip formed integral therewith at one intermediate corner, the convergingv edges of the body portion being diagonal with relation to the longitudinal axis of the strip, said body portion being provided adjacent to its lower corner with a slit which is substantially horizontal and has its ends closed.
